Guardians of the key - Clio Gray

The first in a rich and atmospheric new historical crime series, full of action, vivid characters and conspiracy.

Napoleon and his armies are at the gate of the ancient walled city of Lucca, Italy. In one last desperate attempt to preserve their proud heritage, the Lucchese Council despatch a secret message to their compatriots in England. Unknown to them, ruthless conspirators have got there first. But neither they nor the Council know quite what they are looking for, and the one man who could have told them has just entered a church near the prosperous Italian silk community on the London borders, and slit his own throat.

Witness to this gruesome death is Mabel Flinchurst. When her good friend, a vagrant boy called Toby, is kidnapped, she is caught up in a conspiracy beyond her understanding. She has no idea that the fate of a small Italian city lies in her hands, and that she, and now anyone connected to her, is in mortal danger...
